This study investigated the status of children with obesity before and after the COVID-19 pandemic, and the effects of lifestyle guidance on weight loss among children in Japan. We analysed the data of patients who visited our hospital after check-ups for obesity and evaluated the efficacy of lifestyle guidance. The patients were divided into groups A, B, and C (year 2011, 2019, and 2021, respectively).

Methods: Fifteen female patients who were diagnosed with bimaxillary protrusion and treated with four premolar extractions were selected. The control group consisted of 25 female volunteers with a normal occlusion.
Objective: To evaluate the effects of sliding velocity on friction, particularly at extremely low sliding velocity approximating orthodontic tooth movement.
Materials And Methods: Stainless-steel (SS) 0.022-inch preadjusted brackets and 0.
Objective: To evaluate the influence of vermilion height on the assessment of lip attractiveness by Japanese and Korean orthodontists and orthodontic patients.
Materials And Methods: Vermilion heights were modified by increasing or decreasing the vermilion height in 1.0-mm increments from -3.
Statement Of Problem: The perception of a pleasing smile may differ between the countries in Asia or may be converging on a more internationally pleasing one.
Purpose: The aim of this study was to evaluate the influence of vertical positions of anterior teeth on smile esthetics as assessed by Japanese and Korean orthodontists as well as by orthodontic patients.
Materials And Methods: A standard composite smile was constructed from different females' intraoral and extraoral photographs.
